carrier. 9 and its draw rod 9 and the mold 10. As is well known to those skilled in the art, the centering of the matrix above the mold is accomplished by themovement of the matrix case in'its carrier 9 in one direction and" of the carrier in its supporting frame 8 in a direction at right angles to said first mentioned direction. Vertical movement of the matrix case to accomplish the seating and unseating of the matrix on the top of the mold'is accomplished by the lever 7 operating through the link 12, lever 13 and stay 14, the latter secured to the bridge 1. The lever 13 acts; at its central portion through a rod and spring 11 upon a cross b'ar15 secured at its ends to the vertical rods 16extending through the bridge and secured at their lowerends below the bridge to the frame 8. Between the bridge 1 or its depending fixed projectionsl and the frame 8 is a bulfer 17, clearly shown in Fig. 5 of the drawings and usually made of fiber. This buffer is in the form of a plate pivoted centrally. to the bearing 2. for the centering pin and rotatable on such pivot so as to remov'eits ends from between the bridge 1 and t'l efframe' 8. The portions of the buffer which enter between these elements are formed by cutting away opposite sides of the plate to form notches fitting around the standards 16, so that the buffer adjacent theseno tches will surround a portion of the circumferences of these standards. A spring 18 secured at one end to a projecting portion 19 of the bridge 1 and at itsother end to one end of the buffer 17 maintains the buffer in normal position in which it lies between the bridge 1 and the frame 8 so as to prevent undue upward movement or overthrow of the frame 8, the carrier 9 and the matrix case 3. This is thebufi'er position shown in Fig. 2 and in full lines in Fig. 1.

Secured to the upper part of the bridge in proximity to one of the standards 16 is an'upwardly extending casting 20 which forms a bearing for the vertical spindle 21. Screwretained bearing caps 22 complete the bearing and hold the spindle 21 in position. The spindle is provided with an annular flange 23 fitting above the upper bearing so as to prevent the spindle from downward movement in its bearing. Above the annular collar 23 of thespindle is a lateral extension 24 to which is pivoted by means of the bolt 25, the lever 25' the power end of which is indicated by the character 26. The lower end of the spindle 21 is provided with a buffer removing lever 27 which extends radially from the spindle and downwardly so as to be in position to engage with the buffer 17-when the spindle is rotated. The casting 20 has in the neighborhood of the upper bearing a lateral-extension 28 having an upward flange cut away centrally so as to form upwardly extending lateral stops 29 and 30, between which the lever 25 at all times extends. The lower portion of the notch between the upstanding stops 29 and 30 is formed with a cam surface 31 for cooperation with the underneath edge of the lever 25 so that in moving the lever laterally from its normal position in contact with the stop 29 as shown in full lines in Fig. 1 to its position in contact with the stop 30 as shown in dotted lines in Fig. 2, the turning being accomplished on the vertical pivot formed by the spindle 21, the cam 31 operates to raise the lever so as to accordingly depress the power end 26 of the same and cause it to enter below the cross bar 15, the last motion of the lever being on the horizontal pivot formed by the bolt 25'. The cam 31 however, terminates before the stop 30 is reached, so that after the handle 25 has been raised to its greatest extent by the cam 31 and has passed beyond the latter, the handle may be depressed so as to enter the notch 32 between the cam 31 and the stop 30. The depressing of the handle end of the lever will of course raise the power end 26 thereof and with it the cross bar lf). The latter will raise with it the spindles 16, the frame 8, the carrier 9 and the matrix case 3.

The construction, as has been seen, is such that the operator may move the handle 25 laterally and downwardly in practically a single quick motion which moreover, is wholly controlled by the stops 29 and 30, the cam 31 and the notch 32.

The lateral swing of the lever causes the lever 27 also to swing laterally from the full line position shown in Fig. 1 to the dotted line position shown in the same figure, the end of such lever 27 operating against the buffer 17 so as to rotate it against the spring pressure 18 from full line position to dotted line position of Fig. 1. In Fig. 2 the lever is shown in normal position against the stop 28. In Fig. 4 it is shown in dotted lines in rotated position against the stop 29 but not depressed. In this figure moreover, the lever 27 has moved the buffer 17 away from its normal position and the matrix case has been abnormally raised to correspond with the full line depressed position of the lever 25. The matrix carrier frame 8' in this abnormally raised position abuts (as shown) against the fixed extension 1 of the bridge 1. In all of the views the center pin lever 7 is in its uppermost position. Fig. 3 illustrates the cross slide 5 and its connection with the matrix case 3, the latter being shown in full lines in hooked position with respect to the block and in dotted lines in the abnormally elevated position to which it is raised by the proper manipulation of the lever 25 and the mechanism associated with it. It will be seen from this dotted position in Fig 3 that the matrix case 3 is unlo'cked from thegoross slideg'ef ahd cambe readily slid in {its carrifeni away fro cross slide and thus be withdrawn andcausing it toL-belodkqdtothe: by effecting its connection witll, the; cross block it is merely necessaryto' push, it"into the carrier 9 when the latter is inabnormally :elevatedgp osition; When the "end of the matrix case strikes againsttheplateh which 5 is slightlyfihigherithani the, hooked portion 5 of the cross slide 5, the lowering;

of the case will accomplish its connection with the cross slide, as will readily be understood. y i

In the operation of the device of the present invention the centering pin lever T'is brought to its uppermost posltion as shown in Fig. 2, in which the centering pin 2 is free from the matrices 4 in the matrix vcase 3 and the carrying frame 8 is elevated ,int'o close proximity to the fiber buffer 17, The operator now grasps the handle of lever 25 preferably with the left hand, and moves it laterally away from its normal position against the stop 28-, thus rotating the spindle 21 and causing the lever 27 to remove' the fiber buffer 17 from its normal positlonbetween the carrying frame 8 and the extensions 1' of the bridge; This lateral movement also causes, due to the cam 31,or due to the raising of the handle by the operator as he moves it laterally, a depression of the power end 26 of the lever and its entering under the cross bar 15. With the buffer re moved from normal position and the power end of the lever 26 in. contact with the lower side of the crossbar 15, the operator then depresses the handle of lever 25 so that itenters into the notch 32, thus raising the power end 26, the cross bar 15, the spindles 16, the

carrying frame 8, the carrier 9 and the matrix case 3, the latter being raised tea-position which is abnormal because the frame 8 now contacts withthe underneath side of the extensionl, as shown inFig. l'of the drawings. With the right hand the operator may now readily grasp the matrix case so as to slide said case from its carrier. He may also while retaining the parts in the :position described, seize another matrix case and slide it into position, the forward end passing over hook 5 and striking the plate 5 of the cross slide 5 as a stop. The release of lever 25 will allow the matrix case 3 to drop into hooked connection with the, cross slide 5, this "action causing the raising of the lever 25 and its release from the notch 32.

Moreover, the lever 25 will'be returned laterally to its normal position through the action of the spring 18 which in returning the buffer to normal position will cause the latter to act upon the lever 26 and turn it no m l p ion a machine.
